However, the basic unit of chemical text mining is the recognition of a mentioned chemical entity.
The chemical entity mention recognition (CEM) subtask aims at establishing the location of every mentioned chemical entity within a document [8].
In the calculation of these mentioned chemical properties, Koopmans Theorem [18] provides great facilities to computational and theoretical chemists.
An E factor (exclude water) of 11.5 was calculated for the chemoenzymatic route relative to 55.7 for the mentioned chemical process.
nanoparticles [5], nanorods [6], nanosheets [7, 8] as well as nanowires, hexagonal nanoplates, and microspheres [9, 10] above mentioned chemical techniques have been used.
In addition, a three-dimensional quantitative structure-activity relationship (3D-QSAR) study was performed on the above mentioned chemical series employing comparative molecular field analysis (CoMFA) and comparative molecular similarity index analysis (CoMSIA) techniques.
Given a set of documents, the CDI system returns a list of unique chemical entities for each, whereas the CEM system provides exact occurrence information for all mentioned chemical entities.
Among all these methods as mentioned, chemical reduction in aqueous or organic solvents exhibits the greatest feasibility to be extended to further applications in terms of its simplicity and low cost.
The weight percentage of nitrogen- as well as- the mean number of nitrogen atoms/mole has also been found to be in accord with the above mentioned chemical structures of prepared Mannich bases.
